COOLING SYSTEM 4-11
Water Pump
Water Pump Inspection
•
Check the water pump drainage outlet hose [A] at the
bottom of the water pump for coolant leakage.
If the mechanical seal is damaged, the coolant leaks
through the seal and drain through the passage. Replace
the mechanical seal.
•
Visually inspect the impeller [A].
If the surface is corroded, or if the blades are damaged,
replace the impeller.
Mechanical Seal Replacement
•
Remove the water pump impeller (see Water Pump Re-
moval in this chapter).
•
Pry the mechanical seal flange off with a small chisel [A].
•
Pull the mechanical seal out of the right crankcase with
needle nose pliers. Discard the mechanical seal.
CAUTION
Be careful not to damage the water pum p shaft and
the inner sealing surface of the crankcase.
NOTE
○
Since the replacement mechanical seal has an adhe-
sive coated body, do not apply a liquid gasket to the
exterior surface of the body.
•
Press [A] the m echanical seal [B] by using a suitable 28
mm socket [C] and a bearing driver [D] until its flange
touches the step [E].

If the coolant still leaks through the drainage outlet hose,
the seal and ball bearings is probably damaged. Replace
the mechanical seal, ball bearings, and oil seal by splitting
the crankcase.
•
Split the crankcase (see Crankshaft/Transmission chap-
ter).
•
Remove the water pump impeller.
•
Pull out the water pump shaft from the inside of the right
crankcase.
•
Take the bearing [A] out of the right crankcase, using the
bearing remover.
